So, why are the Onis even still a thing if these two are presumably some of the weaker lads in the Momotaro org, but they can fuck up even mudano with relative ease? Powerscaling in this manga is already fucked.
So, why didn't he do this before? Makes no sense he's only using this ability now and if the mangaka wanted to it, they could've incorporated it in a flashback/explanation as to why they have to always burn their corpses or something...
